Assuming they are both exactly the same battery... at a guess,whichever one you can buy at a cheaper total price, when the shippingcost is added.

You may also wish to consider the seller's reputation and the potentialfor any hassles should it turn out to be necessary to return thebattery.

It seems that many battery sellers advertise genuine brand namebatteries but deliver a so-called equivalent aftermarket battery. SoI would take great care, if you seem to be able to buy a brand namesealed Yuasa battery for a significantly cheaper price than anothervendor, that it is in fact a genuine Yuasa battery.

I've personally had decent luck with Yuasa sealed batteries. Thebargain brand non-sealed batteries seem to be more or lessinterchangeable and don't last longer than a couple of years inmy experience. I haven't had much experience with off-brand sealedbatteries so I can't recommend them or warn against them.
